Getting parts gathered up for my Howa mini build. I can't find the dimensions for a Howa 1500 mini tenon anywhere. Looking for help on barrel tenon dimensions that work well for you guys. Any information is appreciated.
If you are talking about the thread dimensions for the barrel, it is metric, M22x1. I don't know the length of the threading however.
I got one spun up for me from preferred barrels and installed it perfectly. They have a "howage" barrel nut that matches the pitch and makes the install one that a regular guy can do.
I'd recommend them for any other questions you might have, they are a bit slow to answer emails but were very helpful in my re-barrel process.
When I re-barreled the 1st Howa Mini that I'd worked on, I used the pulled factory bbl as a rough standard, and measured to the boltface with a depth mic to see what sort of clearance the factory uses. I had two lathes, and kept the JET set up to cut Imperial threads, and a Precision Matthews with gears for metric threading. However, the 1mm thread for Mini actions requires yet another gear change from the more commonly used 1.5mm threads used on full-size metric actions.
